I just wanted to pop in and advise you use Firefox with No Script (an add on) enabled. It stops all scripts from running on webpages unless you give permission. That means no pop ups, no animated ads, no scroll-over pop ups, no video player etc,. You can whitelist pages, and even individual scripts per page, its a life saver, plus needed security.

Please remember, that Google doesn't give you random adds either. They collect information on your browsing and tailor ads to your browsing history. In fact, they just changed the privacy policy to accelerate targeting ads to users. If you visit food sites, etc, you'll see more ads for food.

In any case, No Scripts saves lives...ok, well, it makes browsing much much better.
